摘要
An electrostatic discharge (ESD) protection circuit with electrical overstress (EOS) and latch-up immunity has a main ESD circuit, a voltage detection circuit and an electrostatic driving circuit. The main ESD circuit is coupled between a first rail and a second rail and has a control end. The main ESD circuit is configured to establish an electrical connection between the first rail and the second rail based on a voltage of the control end. The voltage detection circuit is coupled between the first rail and the second rail for setting the voltage of the control end when a voltage of the first rail is greater than a limiting voltage. The electrostatic driving circuit is used to drive the main ESD circuit when an ESD phenomenon occurs.
